Großer Mittelberg (Lonau)

Lonau is a small village with a population of about 345 situated at an elevation of about 400m in the Harz Mountains of Northern Germany.

The rivers Große Lonau and Kleine Lonau join here.

Kleine Lonau is a tributary of the Große Lonau in Lower Saxony, Germany. It rises at a height of 650 metres and flows through the Mariental valley to Lonau, where it merges with the Große Lonau. It is about 4.2 km (2.6 mi) long.

The Franzosenkopf is a 562 metre high hill in the Harz Mountains of central Germany, which lies about 1.4 kilometres northeast of Lonau in the district of Göttingen in Lower Saxony. To the north of the Franzosenkopf is the Braakberg, a shallow saddle separating them. Flowing around the Franzosenkopf to the east and south is the Kleine Lonau in the valley of Mariental ("Mary's Valley"). To the west the Franzosenkopf is separated from the Kargeskopf hill by the Hackenstieltal valley. The Franzosenkopf is mostly covered in beech, but spruce also occurs in places. It lies entirely within the Harz National Park.

The Große Steinau is a river of Lower Saxony, Germany. It is a 7.8-kilometre-long (4.8 mi) tributary of the Sieber, north of Herzberg am Harz in the district of Göttingen. It rises at about 690 metres near the crags of the Sophienklippe on the Acker. It initially flows in a southwesterly direction, but later swings south before discharging into the Sieber near the small settlement of Aschenhütte, not far from the mouth of the Kleine Steinau. In times of drought the water of the Große Steinau seeps completely into the karst ground before its mouth and reappears about 4 days later at the Rhume Spring. An abandoned village, Steynowe, was probably located in the lower valley of the Große Steinau, but its exact location has not been found.
